Description

一种传输配置信息的方法、装置、设备及可读存储介质 技术领域
本公开涉及无线通信技术领域,尤其涉及一种传输配置信息的方法、装置、设备及可读存储介质。
背景技术
拓展现实(Extended Reality,XR)业务是5G系统所要支持的业务类型中的一种,XR包括增强现实(AR)、虚拟现实(VR)、混合现实(MR)等。下行XR业务的特点包括:具有固定帧率,根据固定周期到达用户设备(UE),但是在固定周期之上会有额外的时延抖动(Jitter),导致实际数据业务到达UE会有所提前或者推迟。
图1是XR业务传输的示意图。如图1所示,在XR业务数据(XRBurst)传输过程中,发送数据帧的帧率为F帧/秒(Frame per second,FPS)。在发送数据帧的每个周期(1/F)中,比如,由发送视频数据帧K对应的数据包k,至发送视频数据帧(K+1)对应的数据包(k+1)这一周期中,时延抖动(jitter)在设定范围内。其中,时延抖动和业务数据的数据包大小分别遵循概率分布(probability distribution)。由于XR业务中时延抖动的存在,业务数据可能提前或延迟到达用户设备101。
为了匹配非整数周期的XR业务,可以提供适配XR业务周期的搜索空间(Search Space,SS)配置。但是使用特定周期模式的SS配置,仍然面临时延抖动的问题,导致XR业务传输时延增加。
如何处理由于XR业务的时延抖动带来的传输时延是需要解决的技术问题。
